About this 1.21ct natural cushion diamond

This 1.21ct natural cushion sits in the classic one-carat band, graded D colour (colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 5303796388. Listed at 8 retailers as of November 1, 2026, with prices from $3,590 to $7,201, a $3,611 spread on the same certified stone. MOH London lists it at $7,201. Cut grade matters more than carat or clarity for visible brilliance. If you can shift budget toward an Excellent or Ideal cut, do it before chasing higher colour or clarity.
